驅動投入位置Y2-斷路位置Y3間的斷路用手動操作機構100 ;及操作接地用真空閥52的接地用手動操作機構120構成 (1)遮斷•斷路器用真空閥51的投入動作（切斷位置Y2-投入位置Y 1 ) 遮斷•斷路器用真空閥51的活動部70是連結在被固定 於第1主軸81的桿臂82。並且，預先在第i主軸81固定桿臂 〇 83 ’經連結金屬件84連接電磁鐵80。即，遮斷.斷路器用 真空閥51只要將第1主軸81朝著順時鐘方向轉動即可投入 ’朝逆時鐘方向轉動即可斷開。 第5圖表示電磁鐵80的內部構造，以下鋼板85、中鋼 板86、鋼管87及中央鐵芯88構成固定鐵芯，在其內部收納 線圈89。中鋼板86的上部設置永久磁鐵90。並將永久磁鐵 罩92、上鋼板93重疊在中鋼板86的上方，以四角落的螺栓 94夾持來組裝電磁鐵80。再者，中鋼板86及永久磁鐵90是 -10- 201025395 形成圓環型，內部貫穿有T字型的活動鐵芯91。一旦使得 線圈89激磁時，活動鐵芯91被中心鐵芯88所吸引。此時， 活動鐵芯91被驅動於圖中下方，投入遮斷·斷路用真空閥 51，使活動部70停止在投入位置Υ1。 並且投入狀態中，遮斷彈簧95及賦予接點接觸力用的 壓接彈簧96是形成儲能狀態，必須以某種手段來抵抗其反 向力。永久磁鐵90的磁通是產生於永久磁鐵90-Τ字型的活 動鐵芯91-中央鐵芯8 8-下鋼板85-鋼管87-中鋼板86-永久磁 鐵90的路徑，在永久磁鐵90-活動鐵芯91間及活動鐵芯91-中央鐵芯88間產生吸引力。在投入狀態中，藉此吸引力抵 抗上述的反向力，維持著遮斷彈簧95、壓接彈簧96的蓄能 狀態。 (2)遮斷•斷路器用真空閥51的斷開動作（投入位置Υ1-切斷位置Υ2 ) • 斷開動作是在與線圈89投入動作時反方向，即與永久 磁鐵的磁通反方向激磁。藉反方向激磁降低永久磁鐵90產 生的磁力，並藉著遮斷彈簧95、壓接彈簧96的力驅動使活 動部70朝斷開方向。 第6圖是說明斷開狀態用的圖。根據上述斷開動作使 第1主軸81朝著逆時鐘方向轉動。此時，位於另外設置在 第1主軸81的桿臂95前端的銷96爲斷路用手動操作機構1〇〇 的滾子101所干涉，使得第1主軸81的滾動停止。此時的活 動部70的停止位置是相當於切斷位置Υ2。 -11 - 201025395 在此’滾子101是藉著銷104固定在以軸102爲中心轉 動的葉片103上。藉著銷95與滾子101的衝突，使葉片103 朝著順時鐘方向轉動，但是滾子101由於第1與止動銷105 的干涉而阻止其轉動，因此維持著斷開狀態。再者，配置 呈捲繞在軸102的線圈彈簧106—方是固定在葉片103，另 一方是固定在外框107上。這是爲了即使投入遮斷•斷路 器用真空閥51解除銷95與滾子1〇1的干涉時，可以使滾子 101預先停止在第6圖的位置之用。 (3) 遮斷•斷路器用真空閥51的斷路動作1 (切斷位置 Y2-斷路位置Y3 ) 斷路操作是將斷路操作手柄108從斷路用操作手柄的 插入孔20插入，與葉片103的銷108卡合，使葉片103朝著 逆時鐘方向轉動。只要梢微使其轉動，使得銷96、銷104 及軸1〇2超過並排在一直線上的止點，即可藉著遮斷彈簧 95的力使第1主軸81及葉片103朝著逆時鐘方向移動。第7 圖表示斷路狀態的說明圖。葉片103與第2止動銷110干涉 ，停止斷路方向的動作。此時的活動部70的停止位置是相 當於斷路位置Y3。並且，斷路用操作手柄108是以正面操 作板2爲支點操作銷109使其跳動，因此不會有受到斷路動 作時的衝擊力之虞。 (4) 遮斷•斷路器用真空閥51的斷路動作2(斷路位置 Y3-切斷位置Y2 ) 201025395 使用第7圖說明此一動作。將斷路用操作手柄108從插 入孔20插入，以插入孔20的上側爲支點和葉片103的銷109 卡合，使葉片103朝著順時鐘方向轉動。此一操作是形成 一邊使遮斷彈簧95蓄能的緩慢操作。在銷96、銷104及軸 1 02超過排列於一直線上的止點回到第6圖的狀態時，使活 動部70停止在切斷位置Y2。 φ (5)接地用真空閥51的投入動作 接著，使用第8圖及第9圖，針對接地用真空閥52的動 作說明如下。接地用真空閥52的活動導體65是與固定在第 2主軸132的桿臂133連結。並且，第2主軸132的桿臂13 4是 經連結金屬件135與接地用手動操作機構120連接。 將接地用操作手柄121從插入孔30插入到承手柄金屬 件122。接地操作手柄121朝著第8圖的下方操作時，承手 柄金屬件122以軸123爲中心朝著順時鐘方向轉動。此時， φ 設置在承手柄金屬件122的銷124和以軸123爲中心轉動的 構件125干涉，使得構件125也朝著順時鐘方向開始動作。 扭矩彈簧126連接在其一端以構件125，另一端以軸127爲 中心轉動的葉片128上。如此，可藉上述動作形成緩緩壓 縮扭矩彈簧126的狀態，最後，連結構件125和扭矩彈簧 126的銷129;連結扭矩彈簧126和葉片128的銷130;及軸 127超過排列在一直線上的止點時，可藉著扭矩彈簧126的 蓄勢力’使第2主軸132朝著轉動方向驅動。其結果，可朝 著上方，即投入接地用真空閥52的活動導體65 (第9圖） -13- 201025395 。再者，投入動作是形成使接觸力賦予遮斷彈簧137及接 點用的壓接彈簧1 3 8的蓄能狀態。 (6)接地用真空閥51的斷開動作 斷開動作是如第9圖表示，向上方操作接地用操作手 柄121。承手柄金屬件122是以軸123爲中心朝著逆時鐘方 向轉動。此時，構件125是與承手柄金屬件122的銷136干 涉，因此構件125也同時動作。軸123、連結構件125和扭 矩彈簧126的銷129、及連結扭矩彈簧126和葉片128的銷 130爲超過排列在一直線上的止點時，藉著投入動作時預 先蓄能的遮斷彈簧137、壓接彈簧138的力，恢復到斷開動 作’即第8圖的狀態。再者，斷開動作中，扭矩彈簧126幾 乎不會蓄能，僅有賴於遮斷彈簧137及壓接彈簧138的蓄能 〇 以下，針對本發明主要內容的聯鎖裝置說明。第10圖 爲前視圖，第1 1圖爲側視圖。並且，將選擇操作對象的選 擇機構7的構造表示在第12圖及第13圖。 選擇機構7主要是以操作板1 5 0和桿1 5 1構成。操作板 150安裝有矩形的構件152，其上下貫穿著桿151。並以構 件152和桿151夾持著復位彈簧154。在桿151的側面固定操 作銷12，該操作銷12貫穿設置在操作板150的橢圓形孔153 °操作板150可沿著設置在正面操作板2的軌道155 (第11 ®)，只在開關裝置1的寬度方向動作。因此，操作銷12 沿著設置在操作板150的橢圓形孔153上下時，操作板150 201025395 不動而僅有桿151上下移動。並且桿151固定有電磁鐵80與 第1主軸81的連結金屬件84干涉的第1聯鎖銷157，及接地 用手動操作機構120與第2主軸132的連結金屬件135干涉的 第2聯鎖銷158。另外，在桿151的上部前端固定著與設置 在斷路用操作操作板的插入孔20及接地用操作操作板插入 孔3 0之遮蔽器鎖定用構件的逆C字型的金屬件156。 正面操作板2設置薄長方型（E字型）的溝槽160，貫 〇 穿該溝槽160的操作銷12形成可沿著溝槽160移動。桿151 由於復位彈簧154而受到經常向下的力，因此操作銷12穩 定位在CB位置、DS位置、ES位置（第1〇圖）。在此，意 味著CB位置是可操作電磁鐵80 ; DS位置是可操作斷路用 手動操作機構100 ; ES位置是可操作接地用手動操作機構 1 2 0的位置。 第10圖是表示操作銷12存在於CB位置，遮斷•斷路用 真空閥50的投入狀態，即活動部7〇存在於投入位置Y1的場 ® 合。遮斷•斷路用真空閥的投入指令是經限位開關161輸 入，因此僅操作銷12存在於CB位置的場合可進行投入動作 。並且’藉著第1聯鎖銷157與連結金屬件8 4的千涉，可阻 止操作銷I2朝向上方的操作。從以上說明，可實現：「僅 限於選擇機構選擇遮斷的場合，可投入遮斷器」、「斷路 或是接地的手動操作中不能進行操作機構的電氣控制」及 「遮斷器投入狀態的場合，不能進行斷路或接地操作」的 3種類的聯鎖。 第14圖爲遮斷·斷路用真空閥5 〇存在於斷開狀態，活 -15- 201025395 動部70存在於切斷位置Y2的場合，隨著斷開動作，使連結 金屬件84朝著上方移動，因此操作銷12朝向上方，更可朝 著DS位置移動。但是，由於第1聯鎖銷157的前端彎曲部 162與連結金屬件84的干涉，可阻止操作銷12朝著ES位置 的移動。即可實現「斷路操作後，可形成接地操作」的聯 鎖。 操作銷12朝著DS位置側移動時，卡合鎖定設置在斷路 用操作手柄的插入孔20之斷路操作用遮蔽器21的第1遮蔽 器鎖件163，及桿151上部的逆C字型金屬件156 (第15圖 )。如第16圖表示，一旦使操作銷12移動至DS位置時，解 除斷路操作用遮蔽器21和第1遮蔽器鎖件163的卡合，可開 啓斷路操作用遮蔽器21。並且，在開放斷路操作用遮蔽器 2 1後的狀態，即使操作銷1 2要朝著上方移動，也會使得斷 路操作用遮蔽器21和第1遮蔽器鎖件163干涉而阻止其移動 。即可實現「僅限於選擇機構選擇斷路的場合，可進行斷 路操作」。 操作銷I2朝ES位置的方向移動時，桿151上部的逆C 字型的金屬件156可解除與鎖定斷路操作用遮蔽器21的第1 遮蔽器鎖件163的卡合，如第17圖表示，與鎖定接地操作 用遮蔽器31的第2遮蔽器鎖件171卡合。在此狀態下，使操 作銷12朝著ES位置移動時，可解除接地操作用遮蔽器31與 第2遮蔽器鎖件171的卡合，可開啓接地操作用遮蔽器31 ( 第18圖）。此一場合與先前同樣地，只要不關閉接地操作 用遮蔽器31’即可藉第2遮蔽器鎖件171阻止操作銷12向上 -16- 201025395 方的移動。並且’第19圖是表示接地用真空閥52投入後的 狀態。由於固定在桿151的第2聯鎖銷158與連結構件135干 涉，因此使得操作銷1 2不能朝向上方移動。根據以上說明 ，可實現「僅限於選擇機構選擇接地的場合，可進行接地 操作」、「接地開關器投入後的狀態，不能操作斷路器及 遮斷器」的2種聯鎖。 再者，如第20圖表示，在接地用真空閥5 1斷開後，即 G 使使操作銷12朝著CB位置的方向移動，仍可以使得桿151 上部的逆C字型的金屬件156與斷路用手動操作機構100的 滾子101干涉而阻止其移動。即可實現「投入斷路器後（ 活動部70回到切斷位置Y2之後），可進行遮斷器的投入動 作」的聯鎖。 以上，根據本發明的開關裝置1，可藉選擇機構7獲得 明確的操作對象，因而可防止作業人員的錯誤操作。並且 ，可藉選擇機構7的操作銷12，機械式地實現開關裝置所 ® 要求的各種聯鎖，提升安全性、可靠性。 〔產業上的可利用性〕 根據本發明，由於可藉著正面操作板的操作銷機械式 實現各種聯鎖，可提供廉價並可提升可靠性的開關裝置。 【圖式簡單說明】 第1圖爲本發明開關裝置的外觀圖。 第2圖爲本發明開關裝置的側剖視圖。 -17- 201025395 第3圖是搭載在本發明開關裝置的開關部的側剖視圖 第4圖是搭載在本發明開關裝置的操作機構的前視圖 第5圖是搭載在本發明開關裝置的電磁鐵的剖視圖。 第6圖是說明搭載在本發明開關裝置的斷路用手動操 作機構的構造圖。 第7圖是說明搭載在本發明開關裝置的斷路用手動操 _ 作機構的動作圖。 第8圖是說明搭載在本發明開關裝置的接地用手動操 作機構的構造圖。 第9圖是說明搭載在本發明開關裝置的接地用手動操 作機構的動作圖。 第10圖是搭載在本發明開關裝置的聯鎖機構的前視圖 〇 第11圖是搭載在本發明開關裝置的聯鎖機構的側視圖 @ 〇 第12圖是搭載在本發明開關裝置的選擇機構的前視圖 〇 第13圖是搭載在本發明開關裝置的選擇機構的側視圖 〇 第14圖是說明以本發明開關裝置從CB位置移動操作銷 的圖。 第1 5圖是說明以本發明開關裝置操作銷從CB位置朝 -18- 201025395 DS位置移動的圖。 第16圖是以本發明開關裝置操作銷存在於DS位置時的 圖。 第17圖是說明以本發明開關裝置操作銷從DS位置朝 ES位置移動的圖。 第18圖是以本發明開關裝置操作銷存在於£8位置時的 圖。 〇 第19圖是以本發明開關裝置接地用真空閥在投入狀態 場合的圖。 第2〇圖是說明以本發明開關裝置從ES位置朝DS位置 移動的圖。 【主要元件符號說明】 1 :開關裝置 2 :正面操作板 Ο 7 :選擇機構 1 2 :操作銷 2〇:斷路用操作手柄的插入孔 21 :斷路操作用遮蔽器 3〇 :接地用操作手柄的插入孔 3 1 :接地操作用遮蔽器 80 :電磁鐵 100 :斷路用手動操作機構 120 :接地用手動操作機構 -19 -Further, in order to achieve the above object, the switch device of the present invention is characterized in that a switch mechanism, a manual circuit breaker or a selection mechanism for operating a manual earthing switch is provided on the front surface of the switch device, and the selection mechanism and the setting are mechanically engaged. In the manual breaker and the shutter of the operation handle insertion hole of the manual grounding switch, when the selection mechanism selects disconnection or grounding, each of the shutters can be opened. H Further, in the present invention, the above contents are applied. Only when the above selection mechanism selects the occlusion, the input command of the above-mentioned occluder is accepted. Specifically, the above-described selection means selects a switch that is turned "on" when the interruption is made, and the above-described interrupter input command is given via the switch. Further, when the above-mentioned interrupter is in the input state, the selection mechanism interferes with the link mechanism of the above-mentioned breaker, and the selection mechanism cannot be operated. When the shutter of the operation handle insertion hole of the above-mentioned manual circuit breaker or the above-described manual earthing switch is opened, the above-mentioned selection mechanism interferes with the above-mentioned selection mechanism, and the above selection mechanism cannot be operated. Further, when the manual ground switch is in the input state, the selection mechanism interferes with the link mechanism of the manual ground switch, and the selection mechanism cannot be operated. Further, in the present invention, when the selection means selects the state of the interruption, the selection means cannot select the ground unless the manual breaker is not opened. When the selection mechanism selects the grounding state, the selection mechanism cannot select the interruption as long as the manual breaker is not inserted. [Effect of the Invention] According to the present invention, it is possible to easily provide a mechanical interlocking switch device having improved safety and reliability. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to Fig. 1. Φ [Embodiment 1] Fig. 1 is an external view showing a switch device 1 according to an embodiment of the present invention. As shown in the figure, the front side of the switch device 1 is provided with a front operation panel 2 and a protective relay 3. The front operation panel 2 is provided with a single-line circuit diagram showing the switch device 1, a pointer 5 indicating an input, a disconnection, and an open state, and an indicator 6° indicating a state of the ground switch; and selecting an interrupt or an open circuit; The selection mechanism 7 for grounding operation; the key switches 8 and 9 for opening and closing the breaker; the insertion hole 20 for the operation handle for the disconnection; and the operation handle insertion hole 30 for the grounding. 201025395 In this embodiment, the machine that operates can be selected by the position of the operating pin 12 of the selection mechanism 7. That is, the circuit is blocked, disconnected, and grounded from the right side. In the case of Fig. 1, the interrupter can be operated. The selection mechanism 7 not only selects an operation, but also realizes interlocking between a series of operations of interruption, disconnection, and grounding. Specifically, it is as follows. The operation of the interrupter can be performed only when the operation pin 12 is selected to be blocked. Further, when the interrupter is put into the state, the operation pin 12 is mechanically locked, and other operations cannot be selected. When the operation pin 12 is selected to be disconnected, the opening operation shutter 21 provided in the insertion hole 20 of the opening operation handle can be opened. Further, the operation pin 12 cannot be moved as long as the circuit breaker 21 is not closed. When the operation pin 12 is selected to be grounded, the grounding shutter 31 provided in the insertion hole 30 of the grounding operation handle can be opened. As before, the operation pin 12 cannot be moved as long as the grounding operation shutter 3 1 is not closed. Further, when the grounding switch is turned on and the switching device 1 is grounded, the operating pin 12 is mechanically locked, so that the interrupter or the circuit breaker is inoperable. Further, when the selection mechanism 7 selects the state of the interruption, the movement of the operation pin 2Q toward the ground side can be prevented as long as it is not the disconnection state. Similarly, when the selection mechanism 7 selects the grounding, the selection mechanism 7 cannot select the blocking as long as it does not move from the disconnected state to the disconnected state. The above "switching device 1 according to the invention, by means of the selection mechanism 7, allows the operating object to be clarified' thus helping to prevent erroneous operation. Further, by operating the pin 12 of the operating mechanism 7 mechanically realizes various interlocks required by the switch device, safety and reliability can be improved. [2010] [Embodiment 2] Next, a second embodiment of the present invention will be described using Figs. 2 to 20 . Fig. 2 is a side cross-sectional view of the switch device 1, and Fig. 3 is a side cross-sectional view of the switch unit 50. As shown in the figure, the switch unit 50 is constituted by a shut-off/circuit breaker vacuum valve 51 and a grounding vacuum valve 52, which are formed by molding a resin 53. The switch unit 50 is arranged in three phases in the depth direction in the drawing. The circuit breaker vacuum valve 51 is a U-shaped vacuum container 49, and accommodates two pairs of contacts therein. The movable conductors 54, 55 are fixed to the connecting conductor 56, and are electrically insulated from the outside by a ceramic insulating rod 57. On the right side of Fig. 3, the fixed conductor 58 on the front side of the switch device 1 is fixed to the bus-side feed line 59, and is connected to the bus bar 60 of the connection switch device 1. On the other hand, the fixed conductor 61 on the back side of the switch gear 1 is connected to the cable 63 via the load side feed line 62. That is, the switching device 1 is a path of the bus bar 60-busbar side feeder 59-fixed conductor 58-active conductor 54-connecting conductor 56-〇active conductor 55-fixed conductor 61-load side feeder 62-cable 63 , power the load. The movable conductors 54, 55 and the connecting conductors 56 are integrally formed. Hereinafter, the movable conductors 54, 55 and the connecting conductors 56 are referred to as movable portions 70. The operation lever 63 coupled to the insulating lever 57 is fixed to the vacuum container 49 by the bellows 64, and the movable portion 70 can be maintained in a vacuum airtight operation. In the case of the shutoff/breaking vacuum valve 51, the movable portion 70 stops the input position Y1 for supplying power to the load, the cutting position Y2 for interrupting the current, and the disconnection position Y3 for protecting the operator from lightning strikes and ensuring insulation performance. 3 locations. The fixed conductor 64 of the grounding vacuum valve 52 is fixed to the load side feeder 62. When it is necessary to perform a grounding operation such as maintenance, the movable conductor 65 of the ground E is brought into contact with the fixed conductor 64. Further, reference numeral 66 denotes a capacitor ’ for voltage detection for determining whether the load is voltage or no voltage. Next, the operation mechanism of the switch device 1 will be described using Figs. 2 and 4 . The operating mechanism is: an electromagnet 80 for driving between the input position Y1 and the cutting position Y2 for the movable portion 7 of the vacuum valve 51 for the circuit breaker and the circuit breaker; and the disconnection between the drive input position Y2 and the disconnection position Y3. The manual operation mechanism 100 and the grounding manual operation mechanism 120 for operating the grounding vacuum valve 52 constitute (1) the opening operation of the circuit breaker vacuum valve 51 (cut position Y2-input position Y 1 ) The movable portion 70 of the vacuum valve 51 is coupled to the lever arm 82 that is fixed to the first main shaft 81. Further, the electromagnet 80 is connected to the i-th spindle 81 fixing lever arm 83' via the connecting metal member 84 in advance. In other words, the circuit breaker vacuum valve 51 can be turned "off" in the counterclockwise direction by rotating the first spindle 81 in the clockwise direction. Fig. 5 shows the internal structure of the electromagnet 80. The lower steel plate 85, the intermediate steel plate 86, the steel pipe 87, and the center core 88 constitute a fixed iron core, and the coil 89 is housed therein. A permanent magnet 90 is provided on the upper portion of the intermediate steel plate 86. The permanent magnet cover 92 and the upper steel plate 93 are superposed on the upper steel plate 86, and the electromagnet 80 is assembled by being sandwiched by bolts 94 at four corners. Further, the intermediate steel plate 86 and the permanent magnet 90 are -10-201025395, and a ring-shaped type is formed, and a T-shaped movable iron core 91 is inserted inside. Once the coil 89 is energized, the movable core 91 is attracted by the center core 88. At this time, the movable iron core 91 is driven to the lower side in the figure, and the vacuum valve 51 for opening and closing is inserted, and the movable portion 70 is stopped at the input position Υ1. Further, in the input state, the blocking spring 95 and the crimping spring 96 for imparting a contact force to the contact form an energy storage state, and it is necessary to resist the reverse force by some means. The magnetic flux of the permanent magnet 90 is generated by a permanent magnet 90-Τ type movable iron core 91 - a central iron core 8 - 8 lower steel plate 85 - a steel pipe 87 - a medium steel plate 86 - a permanent magnet 90, in the permanent magnet 90 - The movable iron core 91 and the movable iron core 91 - the central iron core 88 are attractive. In the input state, the suction force against the above-described reverse force is maintained, and the energy storage state of the blocking spring 95 and the pressure contact spring 96 is maintained. (2) Disconnection and opening operation of the vacuum valve 51 for the circuit breaker (input position Υ1 - cutting position Υ2) • The opening operation is in the opposite direction to the operation of the coil 89, that is, the magnetic flux in the opposite direction to the permanent magnet is excited. . The magnetic force generated by the permanent magnet 90 is reduced by the excitation in the opposite direction, and the movable portion 70 is driven in the off direction by the force of the blocking spring 95 and the pressure contact spring 96. Fig. 6 is a view for explaining the disconnection state. The first spindle 81 is rotated in the counterclockwise direction in accordance with the above-described breaking operation. At this time, the pin 96 located at the tip end of the lever arm 95 provided separately to the first main spindle 81 interferes with the roller 101 of the manual operation mechanism 1 for the disconnection, and the rolling of the first main spindle 81 is stopped. The stop position of the movable portion 70 at this time corresponds to the cut position Υ2. -11 - 201025395 Here, the roller 101 is fixed to the blade 103 which is rotated about the shaft 102 by the pin 104. By the collision of the pin 95 and the roller 101, the blade 103 is rotated in the clockwise direction, but the roller 101 is prevented from rotating due to the interference of the first and the stopper pin 105, and thus the disconnected state is maintained. Further, the coil spring 106 wound around the shaft 102 is fixed to the blade 103, and the other is fixed to the outer frame 107. This is to prevent the roller 101 from being stopped in advance in the position of Fig. 6 when the interference/circuit breaker vacuum valve 51 is used to release the interference between the pin 95 and the roller 1〇1. (3) Disconnection/breaking operation of the vacuum valve 51 for the circuit breaker 1 (cutting position Y2 - breaking position Y3) The breaking operation is to insert the breaking operation handle 108 from the insertion hole 20 of the opening operation handle, and the pin 108 of the blade 103 The engagement causes the blade 103 to rotate in the counterclockwise direction. As long as the tip rotates so that the pin 96, the pin 104 and the shaft 1〇2 exceed the dead center on the straight line, the first main shaft 81 and the vane 103 can be turned counterclockwise by the force of the blocking spring 95. mobile. Fig. 7 is an explanatory diagram showing the state of the disconnection. The blade 103 interferes with the second stopper pin 110 to stop the operation in the disconnection direction. The stop position of the movable portion 70 at this time is equivalent to the disconnection position Y3. Further, since the operation handle 108 for the disconnection operates the pin 109 with the front operation panel 2 as a fulcrum to cause it to jump, there is no possibility of an impact force at the time of the disconnection operation. (4) Interruption and opening operation of the vacuum valve 51 for circuit breakers (opening position Y3-cutting position Y2) 201025395 This operation will be described using Fig. 7. The breaking operation handle 108 is inserted from the insertion hole 20, and the upper side of the insertion hole 20 is engaged as a fulcrum with the pin 109 of the blade 103, and the blade 103 is rotated in the clockwise direction. This operation is a slow operation in which the blocking spring 95 is stored while being stored. When the pin 96, the pin 104, and the shaft 102 are returned to the state of Fig. 6 beyond the stop point arranged on the straight line, the movable portion 70 is stopped at the cutting position Y2. φ (5) Input operation of the grounding vacuum valve 51 Next, the operation of the grounding vacuum valve 52 will be described below using Figs. 8 and 9. The movable conductor 65 of the grounding vacuum valve 52 is coupled to the lever arm 133 fixed to the second main shaft 132. Further, the lever arm 13 4 of the second main shaft 132 is connected to the ground manual operation mechanism 120 via the connecting metal member 135. The grounding operation handle 121 is inserted into the socket metal member 122 from the insertion hole 30. When the grounding operation handle 121 is operated toward the lower side of Fig. 8, the handle shank member 122 is rotated clockwise about the shaft 123. At this time, the pin 124, which is disposed at the handle metal piece 122, and the member 125 which is rotated about the shaft 123 interfere with each other, so that the member 125 also starts to move in the clockwise direction. The torsion spring 126 is coupled to the vane 128 having one end of the member 125 and the other end pivoted about the shaft 127. Thus, the state in which the compression torque spring 126 is gradually compressed can be formed by the above operation, and finally, the pin 129 of the coupling member 125 and the torsion spring 126; the pin 130 that connects the torsion spring 126 and the blade 128; and the shaft 127 exceeds the line. At the time of the point, the second main shaft 132 can be driven in the rotational direction by the accumulating force ' of the torsion spring 126. As a result, the movable conductor 65 (Fig. 9) -13 - 201025395 of the grounding vacuum valve 52 can be put upward. Further, the input operation is an energy storage state in which the contact force is applied to the blocking spring 137 and the contact spring 138 for the contact. (6) Disconnection operation of the grounding vacuum valve 51 The opening operation is as shown in Fig. 9, and the grounding operation handle 121 is operated upward. The handle metal member 122 is rotated in the counterclockwise direction about the shaft 123. At this time, the member 125 is interposed with the pin 136 of the handle metal member 122, so that the member 125 also operates at the same time. The shaft 123, the pin 129 of the coupling member 125 and the torsion spring 126, and the pin 130 that connects the torsion spring 126 and the vane 128 are the breaking springs 137 that are preliminarily stored by the input operation when the pin 130 is connected to the stop line arranged in a straight line. The force of the crimping spring 138 returns to the state of the opening operation, that is, the state of Fig. 8. Further, during the breaking operation, the torsion spring 126 hardly accumulates energy, and only depends on the energy storage of the blocking spring 137 and the crimping spring 138. Hereinafter, the interlocking device of the main contents of the present invention will be described. Figure 10 is a front view, and Figure 11 is a side view. Further, the configuration of the selection mechanism 7 for selecting an operation target is shown in Figs. 12 and 13 . The selection mechanism 7 is mainly constituted by an operation panel 150 and a rod 115. The operation panel 150 is mounted with a rectangular member 152 which penetrates the rod 151 up and down. The return spring 154 is held by the member 152 and the rod 151. The operation pin 12 is fixed to the side of the rod 151, and the operation pin 12 is inserted through the elliptical hole 153 of the operation panel 150. The operation panel 150 can be along the rail 155 (11th) which is disposed on the front operation panel 2, only in the switch The device 1 operates in the width direction. Therefore, when the operation pin 12 is moved up and down along the elliptical hole 153 provided in the operation panel 150, the operation panel 150 201025395 does not move and only the lever 151 moves up and down. Further, the rod 151 is fixed with a first interlocking pin 157 in which the electromagnet 80 interferes with the connecting metal piece 84 of the first main shaft 81, and a second interlocking mechanism in which the grounding manual operating mechanism 120 interferes with the connecting metal piece 135 of the second main shaft 132. Pin 158. Further, a reverse C-shaped metal member 156 which is provided in the insertion hole 20 of the opening operation operating plate and the shutter locking member for the grounding operation operation panel insertion hole 30 is fixed to the upper end of the rod 151. The front operation panel 2 is provided with a thin rectangular (E-shaped) groove 160 through which the operation pin 12 penetrating the groove 160 is formed to be movable along the groove 160. Since the lever 151 receives a constantly downward force due to the return spring 154, the operating pin 12 is stably positioned at the CB position, the DS position, and the ES position (Fig. 1). Here, it means that the CB position is the operable electromagnet 80; the DS position is the manual operation mechanism 100 for the operable disconnection; and the ES position is the position of the manually operated manual operating mechanism 120. Fig. 10 is a view showing the state in which the operation pin 12 is present at the CB position, and the state in which the vacuum valve 50 for the interruption/opening is placed, that is, the movable portion 7 is present at the input position Y1. Since the input command of the vacuum valve for the interruption/opening is input via the limit switch 161, the input operation can be performed only when the operation pin 12 is present at the CB position. Further, by the first interlocking pin 157 and the joining of the metal fittings 84, the operation of the operating pin I2 toward the upper side can be prevented. From the above description, it can be realized that "only when the selection mechanism selects the interruption, the breaker can be put into operation", "the electrical control of the operating mechanism cannot be performed during the manual operation of the disconnection or the grounding" and the "interrupter input state" In this case, there are three types of interlocks that cannot be disconnected or grounded. Fig. 14 is a view showing that the vacuum valve 5 遮 for the interruption/opening is in the OFF state, and the movable portion 70 is present at the cutting position Y2 when the movable portion -20-201025395 is opened, and the connecting metal member 84 is turned upward as the opening operation is performed. Moving, the operating pin 12 is thus facing upwards and is more movable towards the DS position. However, due to the interference of the front end bent portion 162 of the first interlocking pin 157 and the connecting metal member 84, the movement of the operating pin 12 toward the ES position can be prevented. It is possible to realize the interlock of “grounding operation after disconnection operation”. When the operation pin 12 is moved toward the DS position side, the first shutter lock member 163 of the disconnecting operation shutter 21 provided in the insertion hole 20 of the opening operation handle, and the reverse C-shaped metal at the upper portion of the rod 151 are locked by the engagement lock. Item 156 (fifteenth figure). As shown in Fig. 16, when the operation pin 12 is moved to the DS position, the engagement of the disconnecting operation shutter 21 and the first shutter lock 163 is released, and the opening operation shutter 21 can be opened. Further, in the state after the shutter 21 for opening the circuit breaker is opened, even if the operation pin 12 is moved upward, the circuit breaker 21 and the first shutter lock 163 are interfered to prevent the movement. It is possible to achieve "breaking operation only when the selection mechanism selects an open circuit". When the operation pin I2 moves in the direction of the ES position, the reverse C-shaped metal member 156 on the upper portion of the lever 151 can be disengaged from the first shutter lock member 163 of the lock-off operation shutter 21, as shown in FIG. Engaged with the second shutter lock 171 that locks the grounding operation shutter 31. In this state, when the operation pin 12 is moved toward the ES position, the engagement between the grounding operation shutter 31 and the second shutter lock 171 can be released, and the grounding operation shutter 31 can be opened (Fig. 18). In this case, as before, the second shutter lock member 171 can prevent the movement of the operation pin 12 upward by -16 - 201025395 without closing the grounding operation shutter 31'. Further, Fig. 19 shows a state in which the grounding vacuum valve 52 is placed. Since the second interlocking pin 158 fixed to the rod 151 interferes with the joint member 135, the operation pin 12 cannot be moved upward. According to the above description, it is possible to realize two types of interlocking: "Only when the selection mechanism selects the grounding, the grounding operation can be performed", "The state after the grounding switch is turned on, and the circuit breaker and the breaker cannot be operated". Further, as shown in Fig. 20, after the grounding vacuum valve 51 is opened, that is, G moves the operation pin 12 in the direction of the CB position, the reverse C-shaped metal member 156 at the upper portion of the rod 151 can be made. The roller 101 of the manual operation mechanism 100 for breaking is interfered to prevent its movement. It is possible to realize the interlocking of "the input operation of the interrupter can be performed after the circuit breaker is turned on (after the movable portion 70 returns to the cutting position Y2). As described above, according to the switch device 1 of the present invention, the selection mechanism 7 can obtain a clear operation target, thereby preventing erroneous operation of the operator. Moreover, the various interlocks required by the switchgear can be mechanically realized by the operation pin 12 of the selection mechanism 7, thereby improving safety and reliability. [Industrial Applicability] According to the present invention, since various interlocks can be mechanically realized by the operation pins of the front operation panel, it is possible to provide a switching device which is inexpensive and can improve reliability.
